See your eye doctor: For your symptoms of floaters you should see your eye doctor right away to see if it's the sign of a serious problem. As for your other symptoms, they should warrant some further testing.
I believe that it is correct to say that RNA is not replicated, but reproduced. DNA, what I know currently, is the only one that replicates itself.   Plus, to my knowledge, you don't need to copy a RNA strand.
It should be noted that the primer RNA, which is made with a much higher error rate than DNA, is removed upon completion of Okazaki Fragments. A common primer for the DNA replication of chromosomal DNA is a short RNA transcript synthesized de novo by a primase in both prokaryotic and eukaryotic cells (pp. 279-297 (1)).t is also known that the 3â²-end of RNA annealed to template. DNA is not subjected to proofreading by DNA polymerase. Thus, the DNA polymerase can start DNA synthesis from primer RNA without an abortive proofreading process occurring.
